| 152114199 | Central Nervous System (CNS) | A major division of the nervous system consisting of all nerves in the brain and spinal cord | |
| 152114200 | Peripheral Nervous System (PNS) | A major division consisting of all nerves outside the CNS; transmits sensory info towards the CNS, transmits motor messages from brain to rest of body | |
| 152114201 | Somatic Nervous System | Division of PNS that transmits sensory info towards the CNS | |
| 152114202 | Autonomic Nervous System (ANS) | Division of PNS that transmits motor messages from the brain to the body's internal organs and glands | |
| 152114204 | Sympathetic Nervous System | Branch of the ANS that alters activity level of internal muscles, organs and glands to prepare our body physically during emotional or physical arousal | |
| 152114206 | Parasympathetic Nervous System | Branch of ANS that maintains our energy level for normal bodily functioning and physically calms us down after high arousal | |
| 152114208 | Homeostasis | The body's balanced and healthy state | |
| 152114210 | Cognitive Processes | Brain processes of thinking, knowing or mentally manipulating info | |
| 152114212 | Sensation | The response in the brain caused by excitation of a sensory organ | |
| 152114214 | Cerebrum | Two larger hemispheres in the upper part of the brain | |
| 152114215 | Cerebral Cortex | Thin layer of tissue that is the outer layer of the brain | |
| 152114217 | Frontal Lobe | The upper half of each hemisphere; associated with complex mental abilities and the control of voluntary movement | |
| 152114219 | Primary Motor Cortex | Area of the frontal lobe that directs the body's skeletal muscles and controls voluntary movements | |
| 152114221 | Broca's area | Area in the left frontal lobe that controls muscles responsible for production of speech | |
| 152114222 | Parietal Lobe | Located behind the frontal lobe; mostly associated with processing sensations but involved in the coordination of senses and movement | |
| 152114224 | Primary Somatosensory Cortex | Neurons located at the front of the parietal lobe, registers and processes sensory info from receptors in the body | |
| 152114226 | Temporal Lobe | Located on either side of each cerebral hemisphere; associated with processing auditory info, memory, facial recognition, object identification and emotion | |
| 152114228 | Primary Auditory Cortex | Area of the temporal lobes that registers and processes auditory (sound) info | |
| 152114229 | Wernicke's Area | Area of left temporal lobe responsible for the comprehension of language and the formulation of meaningful sentences | |
| 152114231 | Occipital Lobe | Located at the back of each hemisphere; associated with processing visual info | |
| 152114233 | Primary Visual Cortex | Area at the base of occipital lobe that registers, processes and interprets visual info sent form each eye | |
| 152114235 | Corpus Callosum | Think band of nerve fibers in the middle of the brain that connects the left and right hemispheres together and helps the hemispheres to process info together |
